Hi Andy,
I've just sent you an email. Can you tell me a little bit more of what you are trying to achieve. By the sounds of it, when an order is placed you want that information instantly sent across to your website (which is separate from the Shopify store)?
If so we could look at using the Shopify's web hooks to achieve this http://docs.shopify.com/api/webhooks/using-webhooks.
Let me know if you still need help. I’d be more than happy to help.
Thanks,
Andy
